Application flied September 20,1906. smanassaasa Z 7 To all whom it may concern:

Be-it known that I, FRANZ SoHNnLL, a' subject of the Em ror of Austria, residing at Gutenstein, in wer Austria, have in- 5 vented certain new and useful Improvements in Wood Substitutes, of which the following is a s cification.

ThlS invention relates to a new artificial composition that can be worked in the same [0 manner as woodthat is to say, that can be cut, turned, polished, shaped, and fitted in any other manner and possesses in comparison with wood the advantage of being of a lower specific weight. This new compomEI 911% and a notable uantity of silicafi 0 an a a The metho of production of e sai composition consists simply inintimately mixing the above-named ingredients "under addition of, a suitable uantit; of water until at last a thick dou h 1s obtained, from which doughy mass the esired articles :5 canbe shaped by, ressin After the ressin operation the a 10 es are dried an .then.

su mitted to the above-mentioned finishing operations. In practice the method of pre aring the 0 composition is carried out as ollows: A

quantity of u u I n ls nearly correspondin to one-half of the wei ht of the article t at is to be manufacture is mixed with so as to form a thick ulp, to which then wood-dust or ve table fibers" or animal fibers are admixe. suc I ucan be used wood fibers lcellulgse) or the waste fibers o ame om spmmng or animal-fiair. As soon as the mass has become relations of the separate ingredients to each other, as also their relation to the water contained in the pulp of-the cereal-flour, should alwa s .be chosen in such a manner as to obtam finall a thick dough. This dough is thoroughly kneaded prior to the pressing operation of the articles that are to be made,

so that after pressing and drying the com 5 sition assumes the aspect and the techmcal pro rties of wood.

' e as already mentioned, ofthe ingredients of the composition the flour of cereals and the vegetable fiber are taken in'about equal roportions, by weight, and w these two su stances, to ther with the silicate of an alkali, form by at the greatest part of the bulk of the composition, the rcenta of the animal fiber 1s a great dea less.. atisfactory results are obtained with a composition consisting of forty parts, by weight, of flour of cereals with the corresponding quantit 0 water forty parts by weight of ve eta le fibers of wood-dust two parts, y

animal-Hair and eighteen parts,

weight, of by weight, of EEEr-Qfss.

The above-mdicate composition serving as a substitute for wood is particularly appropriate for the-manufacture of bobbins or spools, because it is of lighter weight than wood and besides possesses the properties required for the manufacture of spools, of

capable to be cut and smoothly polis e It be observed that in producing my wood substitute I do not incorporate in 1t resinous or oily constituents. I claim 1. The method of ma which comprises fo 1:

cereal-flour and water an mixing therewith a suitable fiber, adding a silicate of an alkali wood substitute thick pulp of and kneading the same into a homogeneous 4. A wood substitute consisting of flourfrom cereals, vegetable and animal fiber, and water-glass.

5. A wood substitute comprising about forty per cent. flour from cereals, forty per cent. vegetable fiber, two per cent. animalhair and eighteen r cent. water-glass.

In testimony w ereof I have hereunto set l-Aflllllllu any oils, varnishes, or lacquers, or. other my hand in presence of two subscribing witnesses.
